<h3 id="rationale">Rationale:</h3>
<p>Bourne shells are very whitespace sensitive. Adding or removing
spaces can drastically alter the meaning of a script. In these cases,
ShellCheck has noticed that you're missing a space at the position
indicated.</p>
<h3 id="exceptions">Exceptions</h3>
<p>None.</p>
